VirtualPathUtility - Easily forgotten class

This post is really just to remind myself of a class that I always seem
to forget!
System.Web.VirtualPathUtility
is a static class that contains a multitude of methods to use on URLs.
Everything from the simple ‘AppendTrailingSlash’ to the more
sophisticated ‘ToApRelative’. It’s always worth a look at this class to
see if a method you need already exists, but because I don’t need to
mess with URL’s often, I forget it - hopefully this post will help keep
it in my mind!!
